More Information

Overview Manuals Output Isolation Terminal Modules Status Reading Repair Route

Features:

  • Generates the isolated secondary voltages required by an ET 200iSP station.
  • Protects the 24 V DC input against reversed polarity.
  • Carries the Ex de [ib] IIC T4 hazardous-area marking for the documented installation.
Siemens 6ES7138-7EA01-0AA0 forms the power-conversion stage between the external 24 V source and ET 200iSP electronics.

The supply is selected together with its PS terminal module, so the base establishes the field connection while the removable module contains the conversion circuitry.

Certification, Um limit and terminal-module choice define the installation boundary for the complete power-supply position.

The Siemens 6ES7138-7EA01-0AA0 ET 200iSP PS 24 V DC Power Supply is supported for quotations and documentation by Apter Power while OEM availability remains active.

Separation Inside the Power Module

  • Primary Circuit: The 24 V DC primary circuit is electrically separated from the generated secondary voltages.
  • Output Groups: Individual output groups remain isolated from one another inside the module.
  • Station Feed: The separated outputs feed the intrinsically safe electronics of the ET 200iSP station.

Supported Mounting Base

  • Base Compatibility: 6ES7138-7EA01-0AA0 plugs into a TM-PS-A, TM-PS-A UC, TM-PS-B or TM-PS-B UC base.
  • Power Connection: The terminal module establishes the external power connection before the supply module is inserted.
  • Mechanical Match: Mechanical coding and the complete PS order number must agree with the selected terminal module.

Where Operating Information Appears

  • Front Indicator: A front indicator reports the power-supply operating state at the module.
  • Diagnostic Path: Detailed diagnostic information is transferred through the ET 200iSP IM 152 interface module.
  • Alarm Function: The supply itself does not provide a separate process alarm function.

Maintenance Boundary for the Supply

  • Maintenance State: The power-supply module is designed as a maintenance-free ET 200iSP component.
  • Field Repair: Internal repair is not assigned to field personnel.
  • Repair Handling: A failed 6ES7138-7EA01-0AA0 is routed to the manufacturing site for repair handling.
Description
The Siemens 6ES7138-7EA01-0AA0 is the PS 24 V DC power-supply module for an ET 200iSP station. It accepts the station supply and produces the output voltages used by the intrinsically safe distributed-I/O electronics.

Electrical separation inside 6ES7138-7EA01-0AA0 isolates the primary input from the secondary circuits and separates the generated outputs from one another. Reverse-polarity protection is provided at the 24 V input, while a front status indicator reports the module state.

Mechanical integration of 6ES7138-7EA01-0AA0 is through the specified ET 200iSP terminal modules, including TM-PS-A, TM-PS-A UC, TM-PS-B and TM-PS-B UC. The power-supply module is maintenance-free; repair work is assigned to the manufacturing site rather than field servicing.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why is 6ES7138-7EA01-0AA0 not showing an operating indication after wiring?
If 6ES7138-7EA01-0AA0 shows no operating indication, verify 24 V DC polarity, the matching ET 200iSP terminal module, and field wiring before replacing the supply. The status is evaluated through the station’s power and terminal arrangement.
Where should a technician look when 6ES7138-7EA01-0AA0 reports a station power fault?
Start at the front indication of 6ES7138-7EA01-0AA0, then read ET 200iSP station diagnostics and check the IM152 connection and terminal contacts. This separates a power-module issue from a communication or backplane fault.
How does the isolation boundary affect wiring around 6ES7138-7EA01-0AA0?
Keep the 24 V DC supply and field conductors for 6ES7138-7EA01-0AA0 within the specified isolated wiring arrangement. An unverified external return can change the documented circuit relationship.
What must be matched before fitting 6ES7138-7EA01-0AA0 into an ET 200iSP station?
Before fitting 6ES7138-7EA01-0AA0, match the ET 200iSP station family, compatible terminal module, and specified supply path; a mechanically similar terminal does not establish the same electrical connection.
Which replacement checks reduce repeat failures on 6ES7138-7EA01-0AA0?
Record the order number, supply voltage, terminal-module type, status indication, and station diagnostic message associated with 6ES7138-7EA01-0AA0 before removal. These details show whether the fault follows the module or remains in station wiring.
